Ken Sternberg 9996eafe75 web: provide a "select / select all" tool for the dual list multiselect
**This commit**

This commit provides the following new features for dual list multiselect:

- The "available" pane, which has all of the entries that are available to be selected.  Items that
  are already selected will remain, but they're marked with a checkmark and can neither be selected
  or moved.
- The "selected" pane, which has *all* of the entries that have been selected.
- The Pagination control, which in this case only sends an event upstream.

**Plan**:

The plan is to have a master control that marries the available-pane, selected-pane,
select-controls, and pagination-controls into a single component that receives the list of
"currently visible" available entries and keeps the list of "currently selected" entries, as well as
a pass-through for the pagination value that allows it to hide the pagination control if there is
only one page.

A master component *above that* will provide the list of currently visible entries and, at need,
read the value of the master control object for the "selected" list. That component will mostly be
data-only; it's render will probably just be `<slot></slot>`; its duty will be only to map entries
to string keys Lit can use, and to provide the lists we want to provide and the pagination ranges we
want to show.

Some judicious use of grid will allow me size the controls properly with/without the pagination
control.

Status and Title are going to be in the master control.

A <slot> will be provided for Search, but I have no plans to integrate that into this control as of
yet.

There is already a planned fallback control; the multi-select experience on mobile is actually
excellent, and we should exploit that appropriately.

web: basic cleanup of buttons (#6107)
* web: basic cleanup of buttons

This commit adds Storybook features to the Authentik four-stage button.
The four-stage button is used to:

- trigger an action
- show that the action is running
- show when the action has succeeded, then reset
- show when the action has failed, then reset

It is used mostly for fetching data from the server.  The variants are:

- ak-spinner-button: The basic form takes a single property argument, `callAction` a function that
  returns a Promise (an asynchronous function).
- ak-action-button: Takes an API request function (which are all asynchronous) and adapts it to the
  `callAction`. The only difference in behavior with the Spinner button is that on failure the error
  message will be displayed by a notification.
- ak-token-copy-button: A specialized button that, on success, pushes the content of the retrieved
  object into the clipboard.

Cleanup consisted of:

- removing a lot of the in-line code from the HTML, decluttering it and making more explicit what
  the behaviors of each button type are on success and on failure.
- Replacing the ad-hoc Promise management with Lit's own `Task` handler. The `Task` handler knows
  how to notify a Lit-Element of its own internal state change, making it ideal for objects like
  this button that need to change their appearance as a Promise'd task progresses from idle →
  running → (success or failure).
- Providing JSDoc strings for all of the properties, slots, attributes, elements, and events.
- Adding 'pointer-events: none' during the running phases of the action, to prevent the user from
  clicking the button multiple times and launching multiple queries.
- Emitting an event for every stage of the operation:
  - `ak-button-click` when the button is clicked.
  - `ak-button-success` when the action completes. The payload is included in `Event.detail.result`
  - `ak-button-failure` when the action fails. The error message is included in `Event.detail.error`
  - `ak-button-reset` when the button completes a notification and goes back to idle

**Storybook**

Since the API requests for both `ak-spinner-button` and `ak-action-button` require only that a
promise be returned, Storybooking them was straightforward. `ak-token-copy-button` is a
special-purpose derivative with an internal functionality that can't be easily mocked (yet), so
there's no Storybook for it.

All of the stories provide the required asynchronous function, in this cose one that waits three
seconds before emitting either a `response` or `reject` Promise.

`ak-action-button`'s Story has event handler code so that pressing on the button will result in a
message being written to a display block under the button.

I've added a new pair of class mixins, `CustomEmitterElement` and `CustomListenerElement`. These
each add an additional method to the classes they're mixed into; one provides a very easy way to
emit a custom event and one provides a way to receive the custom event while sweeping all of the
custom event type handling under the rug.

`emitCustomEvent` replaces this:

``` JavaScript
this.dispatchEvent(
  new CustomEvent('ak-button-click', {
    composed: true,
    bubbles: true,
    detail: {
      target: this,
      result: "Some result, huh?"
    },
  })
);
```

... with this:

``` JavaScript
this.dispatchCustomEvent('ak-button-click', { result: "Some result, huh?" });
```

The `CustomListenerElement` handler just ensures that the handler being passed to it takes a
CustomEvent, and then makes sure that any actual event passed to the handler has been type-guarded
to ensure it is a custom event.

**Observations**

*Composition vs Inheritance, Part 1*

The four-state button has three implementations.  All three inherit from `BaseTaskButton`:

- `spinner`
  - provides a default `callAction()`
- `action`
  - provides a different name for `callAction`
  - overrides `onError` to display a Notification.
- `token-copy`
  - provides a custom `callAction`
  - overrides `onSuccess` to copy the results to the keyboard
  - overrides `onError` to display a Notification, with special handling for asynchronous
    processing.

The *results* of all of these could be handled higher up as event handlers, and the button could be
just a thing that displays the states.  As it is, the BaseStateToken has only one reason to change
(the Promise changes its state), so I'm satisfied that this is a suitable evolution of the product,
and that it does what it says it does.

*Developer Ergonomics*

The one thing that stands out to me time and again is just how *confusing* all of the Patternfly
stuff tends to be; not because it's not logical, but because it overwhelms the human 7±2 ability to
remember details like this without any imperative to memorize all of them. I would like to get them
under control by marshalling them under a semantic CSS regime, but I'm blocked by some basic
disconnects in the current development environment.  We can't shake out the CSS as much as we'd like
because there's no ESPrima equivalent for Typescript, and the smallest bundle purgeCSS is capable of
making for just *one* button is about 55KB.  That's a bit too much.  It's a great system for getting
off the ground, but long-term it needs more love than we (can) give it.

* Prettier has opinions.

* Removed extraneous debugging code.

* Added comments to the BaseTaskButton parent class.

* web: fixed two build errors (typing) in the stories.

* web: prettier's got opinions

* web: refactor the buttons

This commit adds URL mocking to Storybook, which in turn allows us to
commit a Story for ak-token-copy-button.

I have confirmed that the button's algorithm for writing to the
clipboard works on Safari, Chrome, and Firefox.  I don't know
what's up with IE.

* ONE BYTE in .storybook/main blocked integration.

With the repair of lit-analyze, it's time to fix the rule set
to at least let us pass for the moment.

* Still looking for the list of exceptions in lit-analyze that will let us pass once more.

* web: repair error in EnterpriseLicenseForm

This commit continues to find the right configuration for
lit-analyze.  During the course of this repair, I discovered
a bug in the EnterpriseLicenseForm; the original usage could
result in the _string_ `undefined` being passed back as a
value.  To handle the case where the value truly is undefined,
the `ifDefined()` directive must be used in the HTML template.

I have also instituted a case-by-case stylistic decision to allow
the HTML, and only the HTML, to be longer that 100 characters
when doing so reduces the visual "noise" of a function.

web: Add storybook (#5865)
* \#\# Details

web: replace lingui with lit/localize

\#\# Changes

This rather massive shift replaces the lingui and `t()` syntax with lit-localize, XLIFF, and the `msg()`
syntax used by lit-localize.  90% of this work was mechanized; simple perl scripts found and replaced
all uses of `t()` with the appropriate corresponding syntax for `msg()` and `msg(str())`.

The XLIFF files were auto-generated from the PO files.  They have not been audited, and they should be
checked over by professional translators.  The actual _strings_ have not been changed, but as this was
a mechanized change there is always the possibility of mis-translation-- not by the translator, but by
the script.

* web: revise lit/localize: fix two installation issues.

* web: revise localization

TL;DR:

- Replaced all of Lingui's `t()` syntax with `msg()` syntax.
- Mechanically (i.e with a script) converted all of the PO files to XLIFF files
- Refactored the localization code to be a bit smarter:
  - the function `getBestMatchLocale` takes the locale lists and a requested locale, and returns the
    first match of:
    - The locale's code exactly matches the requested locale
    - The locale code exactly matches the prefix of the requested locale (i.e the "en" part of "en-US")
    - the locale code's prefix exactly matches the prefix of the requested locale
    This function is passed to lit-locate's `loadLocale()`.
  - `activateLocale()` just calls `loadLocale()` now.
  - `autodetectLanguage` searches the following, and picks the first that returns a valid locale
    object, before passing it to `loadLocale()`:
    - The User's settings
    - A `?locale=` component found in `window.location.search`
    - The `window.navigator.language` field
    - English

The `msg()` only runs when it's run.  This seems obvious, but it means that you cannot cache
strings at load time; they must be kept inside functions that are re-run so that the `msg()` engine
can look up the strings in the preferred language of the user at that moment.

You can use thunks-of-strings if you really need them that way.

* Including the 'xliff-converter' in case anyone wants to review it.

* The xliff-converter is tagged as 'xliff-converter', but has been
deleted.

* web: conversion to lit-localize

The CI produced a list of problems that I hadn't caught earlier,
due to a typo ("localize build" is correct, "localize compile" is
not) I had left in package.json.  They were minor and linty, but
it was still wise to fix them.

* web: replace lingui with lit/locale

This commit fixes some minor linting issues that were hidden by a typo in package.json.  The
issues were not apparently problematic from a Javascript point of view, but they pointed
to sloppy thinking in the progression of types through the system, so I cleaned them
up and formalized the types from LocaleModule to AkLocale.

* web: replace lingui with lit/localize

One problem that has repeatedly come up is that localize's templates do not produce
JavaScript that conforms with our shop style.  I've replaced `build-locale` with
a two-step that builds the locale *and* ensures that it conforms to the shop style
via `prettier` every time.

* web: replace lingui with lit-locale

This commit applies the most recent bundle of translations to the
new lit-locale aspect component.  It also revises the algorithm
for *finding* the correct locale, replacing the complex fall-back
with some rather straightforward regular expressions.

In the case of Chinese, the fallback comes at the end of the
selection list, which may not be, er, politically valuable
(since Taiwan and Hong Kong come before, being exceptions that
need to be tested).  If we need a different order for presentation,
that'll be a future feature.

* web: replace lingui with lit/locale

Well, that was embarassing.

* web: add storybook

The delta on this didn't make any sense; putting it back causes no behavioral
changes.

* web: add Storybook

Fixed a typo in the package.json that prevented the TSC check
from passing.

* web: incorporate storybook

This commit includes a number of type and definitional changes needed to make lit-analyze pass. In
most cases, it was a matter of reassuring Lit that we were using the right type and the right type
converter, or configuring the property such that it should never be called as an attribute.

The most controversial change is adding the 'no-incompatible-type-binding' to the LIT analyzer
configuration (found in `tsconfig.json`). This "routes around" lit-analyzer not doing very well
understanding that some HTML objects can have generic property types, as long as the renderer is
configured correctly.

The 'no-missing-import: off' setting is required as lit-analyzer also does not use the tsconfig
`paths` setting correctly and cannot find objects defined via aliases.

It's a shame JSON can't support comments; these should be in the tsconfig.json file directly.  As it
is, I've started a README file that includes a section to record configuration decisions.

Deleted the lingui.config file as we're not using it anymore
